Supported 'at:the= forward end of the chassis or frame: I I are-two vertical frame :members I I.

Disposed between :.the.:- -pairs-: of.-.-rails,u adjacent the outer edges thereof iare longitudinally spaced 1 rollers22 which'form betweenthe'railsschannels 23, lini which plates 24';aretslidablyrlmounted; Each plate 24 has azbearingxportion; fonanagi tator blade shaft 25;:oncwhich shaft issecurednan' agitator blade unit, as at126.: The unit. 26 includes curved: segments 21 of :a circle which are adapted to be brought into close proximity tothecontour ofntheitroughj 2B;='in which the -mixture: is:to.-be prepared.

On the shaft 25, adjacent the.-frame.; I1,3 are secured :sprockets '1 29; around which pass drive chains 30;whicha1sopass around other sprockets 3 I .on a supplemental drive shaft :32;

Pivoted to each side of theshousing; II as.;at 33,1 are operatingi levers :34 having ;count.er-.-balance weights :35 at their'rear ends. These levers are pivoted to the plates 24, as at 36, and-also include forwardly extendinghand-grip portions 31; By this construction: the blade unit c26'may be moved into raised and. lowered positions with respectto the-mixingtrough 28.

Supported on the bottom plate 4| of the chase sis-,l within-the housing Il, .is. asuitable drive motoror engine as at 42, which, in the construetion -shown,isin the form ofa small gas engine, It.will-be understood, however, that any type-of power can beutilized; The engine or motor 42 operates a. main drive shaft 43 supported in suit: able bearings as at 44, between. which bearings is a clutch 45 controlled by a lever ,46. On the shaft 43 is-a pinion 41for actuating a gear-48 on an idler shaft-49.- On the shaft 49 isapinion 5ftwhich meshes. with .a gear. 51 on .a, supple,- mental Idrive shaft-v32, thus producing, the drive to the drive chains 30"for actuating the blade unit" 26;" as 'will' be apparent; v The trough 2 8 is supportedon spacedileg members '-52whic'hmain tains the bottomof th'eitroughabove asupporteing' surface for-= engagement by a wheeling or conveyingunit '53 which is shown in Fig: 5:

It will also appear thatsthe side walls of. the

Afteriiazb'atch" ofi concrete... mortar: or: the like f has: been: mixed; the -agitator nels moved into raised position and, then, the unit 53 is moved beneath the trough to lift the same and then conveyed to a point of delivery. The unit 53 comprises a pair of side rails, one of which is seen at 55 in Fig. of the drawing, braced by cross-straps, as at 56. Pivoted to the lower ends of the rails 55 are rubber-tired wheels, one of which is seen at 51. It will be understood that the lower portions of the rails 55 are spreadapart a distance greater than the width of the trough 28 to dispose the wheels 5! beyond the limits of the side walls of the trough. Supported between the rails 55, as at 58, are a pair of curved fingers 59, which are adapted to slip beneath the trough and form supports for maintaining the trough in substantially horizontal position in conveyance of the trough to a position for use.

On the side rails 55 are V-shaped leg members 60, which in conjunction with the wheels 51, will maintain the trough in position while the contents are being consumed. It will thus be apparent that several troughs can be utilized on a job and conveyed to a position for use, at which position, the troughs may be lowered to be supported on their feet 52. On the other hand, in other uses, the trough can be left in the unit 53 until the contents is removed and then wheeled back for the mixing of a new supply.

Units of the type and kind under consideration can be practically used on a fairly large job serving several men and, at the same time, can be very practically used in a small job where one or two men are performing the desired operations. By reason of the construction of the apparatus, the same can be produced economically and can be conveniently transported from place to place as a trailer, suitable means being provided to couple the same with a car or truck.
